Red flags in UK company accounts: how to read between the lines

Most UK insolvencies don't come out of nowhere. The signals were on Companies House for months before the news hit; the directors knew it, the auditors usually knew it, and anyone who actually read the accounts knew it too. The problem is almost no-one reads the accounts.

You don’t need to be a chartered accountant to get useful signal out of UK company accounts. A 10-minute read of the last two filings is enough to spot most distress patterns.

1. Late or missing filings

Accounts overdue by even a few weeks is a soft red flag; overdue by months is a hard one. It usually means a struggling finance function, a dispute with the auditor, or worse. Our Companies House filings explainer covers what each filing means.

2. Sudden switch to dormant or micro-entity accounts

A company that previously filed full or abridged accounts switching to dormant accounts has either genuinely stopped trading — or is trying to publish less.

3. Negative net assets

Liabilities exceed assets. Common in early-stage startups (funded by loans/shareholder funding) but a serious warning sign in a mature trading business.

4. Falling cash, rising creditors

Cash at bank dropping while trade creditors rise is the cash-flow squeeze that precedes most insolvencies.

5. Long-overdue debtors

If debtors are huge relative to turnover, the company is funding its customers. One large customer failure can take the supplier down with it.

6. New charges registered late in the cycle

A flurry of new charges — especially debenture-style fixed and floating charges — in the months before accounts fall due often means rescue financing is being lined up.

7. Going-concern qualifications

In audited accounts, a material-uncertainty paragraph in the auditor’s report is the loudest warning the system produces. Read it.

Putting the signals together

Any one of these in isolation is rarely fatal. Three or four together — late accounts, falling cash, new charges, multiple director resignations — is the pattern that precedes most small-company failures by 6–12 months.
